If you did it by the book you should still have a vmlinuz-2.2.16-22 in
the /boot folder(atleast I have anyway). Make another entry in lilo.conf identicle to
the other
with the thing pointing to the 2.2.16-22 file instead and when you save
be sure to run lilo again...

I know this is a question forum, but I'd just like to state my advice on
what distrubutions I like, as I think this might be a good tip to the
newbies:
I've used a number of distribution over the last three years. Started
on LinuxPPC 1999 Q4, then RedHat 5.2->7.0, SuSE 6.0->7.0 (or was
it 6.4?), Slackware 7.1 and now Debian.
My advice to newbies is: First, try RedHat to get to know your way
around Linux. Then go for Debian. Why? Debian has a functionality
known as apt-get that allowes you to get your computer to fetch
software from the net itself and install it. The packeage system of
Debian is wonderfull, and combined with a frontend line
ximian(.com)'s RedCarpet, and man you have one great OS!
If you get a CD set, instead of download, Debian may have a good
installation guide, so you might also consider going right for it with
that one in your hand. (I downloaded it, so I don't know how good it
is)
My favourite distros still remain Slackware and Debian, as SuSE is
just to much, LinuxPPC is just for Macs (but the best of the
mac-distros.), and RedHat is to special (though easy) for me (I could
not even compile a new kernel on 7.0 as it was using beta software
by default....). Slack I would not reccoment for beginners, as it is to
"basic" and lack several of the configuartion tools that newbies would
like. It also lacks a powerfull packeaging system like .deb or .rpm.
Happy linuxing!

I highly agree with Joshua about scrapping the raid0 for something better.
Backup and restore is the best way.... Think about this -
Raid0 - Striped array / no fault tolerance, one dies all data is gone...
Raid 1 - Mirrored and Duplexed array (high overhead for ECC, simple to
recover from, doubles the read trans rate but only writes at normal disk
speeds)
Raid 4 - Independent Disks with shared parity Disk. (High read
speeds, Low ECC overhead, Complex design, Worst Write trans rate,
Difficult to rebuild)
Raid 5 - Independant Data Disks with distributed parity blocks (Highest
Read trans rate, Medium Write rate, Low ECC overhead, Difficult to rebuild
)
Source of all that came from
http://www.acnc.com/raid.html
My question for Joshua ;)
I've only used raid 1 and 5 software on my linux stuff and the howto I've
got only goes into recovering the 1 or 5 failure. Is it safe for me to
assume that since the raid0 is dependent on all drives (Striped with no
parity)that using raidhotadd won't work with the raid0 config?
Just curious since at some point I'll probably have to explain that to
someone around here who thinks they know something ;)

As I remember the rap on Debian was that they spend so much time
testing everything that they are always way behind everyone else
in terms of having the latest and greatest stuff. Is this still
true?

Although I've posted to newsgroups occasionally in the past (I've mostly
found answers in FAQs or webpages), this has been my first Linux related
post and I'm very grateful for all of your helpful responses.
The PC in particular that I backed-up is a cludged 486 running Slackware
7.1 (actually Zipslack but that's a long and painful story!) with a 209MB
partition (includes everything), plus a 32MB swap partition.
The --one-file-system option sounds useful in this situ. Also, due to the
syntax reqt's, I had to exclude cdrom, proc and mnt without using '/', then
I guess they would be excluded no matter if they appeared anywhere on the
dir tree as dirs or files!
In my humble opinion this might make a case for a future amendment to tar
to allow for '/' so as to distinguish between dirs and files OR another
option for specifying dirs only (which is perhaps the less confusing
alternative) :)
Thanks once again, Scrumpy

To add to the other posts. Add an append line to the boot command :
console=ttyS0,9600n
or whatever, your serial port and it's speed is.
Then you can see it even boot through a terminal.
I've done that - looks cool :-)

OTOH, there's RH7.0: All the lastest stuff -- but it's broken
in umpteen different places.
I've been running RH fairly happily since 2.something. Stay
away from *.0 releases and you're generally OK.

Reply-To: [EMAIL PROTECTED]
Hey there... ]) powered by Linux 2.4.2-ac28 ([
I have spent the last few days trying to figure out how to get my printer to
print the whole page instead of cutting off the last approx. 15mm.
I'm running a Mandrake 7.2 system with CUPS 1.1.4. My printer is a HP Deskjet
610C which worked perfect some weeks ago and now suddenly makes those problems
with CUPS. I've tried all drivers which were included in the original CUPS and
I even installed the HP developed drivers - without any change.
I cannot be a hardware problem because I recently checked that by printing out
some test stuff under Windows (*moan*).
I do have the impression that the top margin is too large and that's why it
stops printing before it is actually finished (some lines are being cut off).
I've tried to find a way to fix that. I changed the Imageable Area in lp.ppd
and experimented with several mpage and ghostscript options -- no luck either.
In fact - none of the changes had any affect...?!
Does anybody know how I can finally get the whole page on the sheet? :-)
Thanks in advance 4 every help - and have a nice weekend, Matt.

That's true if you go with the "stable" version, which is analagous to
the "Linux 2.even.*" kernel stream; the stable version primarily gets
augmented by bug fixes.
On the other hand, if you take the riskier option of the "unstable"
version, you get pretty bleeding edge stuff, paralleling "2.odd.*"
kernels. Some risks of breakage.
The cycle of time between stable releases has been pretty long, so
they've been working on having some additional versions, namely the
"testing" versions of Debian, where when packages get _somewhat_
tested, so they are known not to cause _desparate_ breakage to
anything, they migrate from "unstable" to "testing."
[The major breakage is typically with stuff like Perl or XFree86; when
major new versions come out, it takes a while for it to stabilize to
the point of functioning on the diverse set of systems out there...]

And that's exactly what works. The instructions for several things in
the Personal edition of 7.0 are incomplete or misleading. (Try following
the instructions for setting up a TV card if you don't have WinTV card.
You'll never get it working).
I bought the Pro version of 7.1 and it's interesting to see how much
more accurate the information is in the manuals for Pro.

AFAIK, if *any* of the disks in a raid0 dies, the entire array (as an
entity) is gone. It *may* be possible, via some low-level tools, to
get data off of the surviving drives. But there'll be no recovery
of the array itself.

Yes and no. Anyone, at any time, is perfectly welcome to ride the
unstable tree. Currently I'm running an unstable Debian system on my laptop
because the UI, namely KDE, is cutting edge. Rock solid stable. The only
thing that I am actively aware as not being the latest version is the kernel
which I package on my own (trivial, really). Anything which isn't on the
latest version (Xfree86, for example, is 4.0.2) is because the latest version
was released only a short time ago.
Yes, unstable breaks from time to time but that is why it is named
unstable. Personally I run unstable for my 'workstation' uses. The laptop is
riding unstable, my home machine will eventually have unstable installed on
it, etc. For 'server' uses I ride stable. At home I've got a general purpose
server. NFS, SMB, NAT, FTP, HTTP, Mail, SSH, yadda, yadda, yadda. Put it on
stable, run updates every now and again, monitor security.debian.org and
haven't had any problems with it. Reason for that split is if my
'workstation' machines get broken I'm not worried as my server, which will
rarely break, is the one doing the critical work. To me that is the best of
both worlds for it is rare that I need the absolute latest version of Apache
or Exim or Samba, etc.
Finally there is another option available to Debian. That is the source
tree. apt-get source foo will get you the sources for foo so you can build
your own package. If you absolutely /must/ have something that Debian doesn't
provide and you don't want to upgrade, in most cases, you can grab the
appropriate source package, make the changes you need, repackage and install.
A recent example of this from my laptop is slrn. To access some
newsgroups for work I needed SSL compiled into slrn. As of 0.9.7.0 ssl was
put into the main tree (Davis kept a separate archive for the SSL version if
not a separate 'tree'). What I did was kludgy, it is certainly not what I
would recommend for use by others, but it got SSL compiled in. I nabbed the
source (apt-get source slrn) which was of 0.9.6.3. Downloaded the source for
0.9.7.0 (www.slrn.org). Unpacked the source for 0.9.7.0 into the directory
the apt-get source created. Modified debian/rules to enable --with-ssl on the
configure step of the packaging process. Ran the build process and ended up
with a slrn package. It identifies itself as the latest from the author
(0.9.6.4-16) but is 0.9.7.0 with ssl. Works fine until there is an offical
debian release of 0.9.7.0 with ssl.
ii slrn 0.9.6.3-16 threaded news reader (fast for slow links)
{grey@antelope:~} slrn --version
Slrn 0.9.7.0 [2001-03-28]
S-Lang Library Version: 1.4.4
I found all of this insanely easy to do. Of course this article will go
out with the version of slrn on my server...
{grey@teleute:~} slrn --version
Slrn Version: 0.9.6.2 (Aug 31 2000 19:47:46)
S-Lang Library Version: 1.4.1
...but even so there aren't many changes from 0.9.6.2 and 0.9.7.0 that I
/need/ right away. If I do, I can either try to compile as above or simply
switch over my newsreading to my laptop.
Anyway, rambling post, point is that yes, Debian takes a long time between
major stable releases. However, they are exactly that, STABLE. Of all the
distributions of Linux I would not run any commercial application outside of
Debian stable, they have never let me down. On the flip side I don't feel
like I'm ever wanting for the latest and greatest where it counts, end-user
applications. There are several different methods that I can obtain the
latest and greatest for my own personal needs. To me it really is the best of
both worlds.

I've only used linuxppc on Macs so far, but I'm getting an Intel laptop
and standardizing on some other Linux in the hopes of finally actually
being able to print a file in Linux.
I was intrigued by Nicholas Petreley's article in Linuxworld about the
Debian upgrade system "apt-get", getting around the dependency problems
with rpm installations I've encountered lots in linuxppc. The
Corel-Linux distribution is apparently based on Debian. Does "apt-get"
work in Corel-Linux or are you constrained to use the Corel
install/update utility?
The other choice I can find easily seems to be Linux Mandrake, which is
RedHat based I gather.

Printing to a jetdirect connected printer is a peice of cake as long as
you are using TCP/IP. In my experience I've found that it doesn't seem
to matter what you call the queue on the Jetdirect box, although raw and
text are the "official" ones.
However, there _are_ times when printing via a _Windows_ share can be
useful. For example, on my Win2K box, I share out my Brother HL-1040
attached to a Jetdirect 300EX because I've run Linux distros that don't
allow you to use print filters with remote printers but do allow you to
use them with Windows shared printers via Samba. So I just printed to
the share off my Win2K box that pointed to the Brother on the Jetdirect
box.
I don't understand why some distros let you use filters with remote
printers and others don't.
